Homogenization of a nickel-base superalloy ingot material
Abstract
The kinetics of homogenization of cast-ingot material of a typical nickel-base superalloy, Waspaloy, were determined and compared to previous measurements for single crystals. The observed kinetics for the ingot material were approximately twice as fast as those for the single crystal, an effect attributable to concomitant grain growth and hence enhanced (pipe) diffusion along grain boundaries in the polycrystalline condition.
